I installed libusb-win32-filter-bin-0.1.12.0.exe to c:\LibUSB-Win32. I compiled the sys and dll (cd /cygdrive/c/LibUSB-Win32/src; make all).
This shouldn't be necessary; simply installing libusb from Cygwin setup should be enough.
I installed the USRP windows driver following the description at http://gnuradio.org/trac/wiki/USRPWindowsDriverInstall When i look at the driver property in the device manager i see that 'the device is working properly'. The libusb test program detects the device as well. When i run ./test_usrp_standard_rx.exe i get: usb_control_msg failed: usb_control_msg: sending control message failed, win error: A device attached to the system is not functioning.
This appears to be a new issue with version 0.1.12.0-1 of libusb.
rx_overun xfered 1.34e+08 bytes in 4.25 seconds. 3.158e+07 bytes/sec. cpu time = 0.297 noverungs = 1 I get the first error message with any tool i try to access the USRP (usrp_rx_cfile.py for example). usrp_oscope.py displays the same error message but i see the signal graph (but almost no amplitude).
It sounds like everything is working despite the error message. I also get the same error message with the new libusb, but my GNU Radio applications still seem to work ok.
I will look into the problem and see what I can find out. For now you can either use it as is or go back to version 0.1.10.1-3 of libusb.
